And Comcast cannot send read receipts.
Delivery receipts are sent by the server (but that does not mean the
receipient read the message).
Read receipts are sent by the client app (Outlook) *if* the client is set to
send them (I always have read receips turned off)
Unless both you and the other side are using mail servers to store messages
that neither of you can control, nothing can be proved either way:
PST is a local file, and it is easy to have anything you please there, dated
any date you want.

You can't prove a negative.

I am in a legal dispute with a con man who is stating that he sent me an

arbitrator (altered) that said he sent it to me in Jan 20 2007 changing
our
contract terms. This never happened I would never have accepted it. The
arbitrator ruled that he must prove he sent it and I received it. Three
months later he comes in with a read receipt saying I opened it 15 hours
later. Both of these were printed out and no one has seen the actual
emails
he is stating he has. I have requested a subpoena to look at his computer
to
see these. His ISP is Comcast and he uses outlook. He stated in his reply
that Comcast sent him a read receipt showing I opened this email.

How can I prove these were never sent or the read receipt was sent????
